Rated 3 out of 5 by from Reasonable price, reasonable q A reasonably priced decking screw but needs care when using a cross head drill bit, easy to strip the cross and make screwing in or out very difficult.

Rated 1 out of 5 by from Cheap screws Just cheap rubbish, must be Chinese steel, head end burrs easily. Screws themselves bend very easily, worst screws I’ve ever bought, stay clear.

Rated 1 out of 5 by from Waste of money I only bought these because the standard decking screws were out of stock. These prima donnas will waste your time while you try everything you know to use them. Self tapping ? - joke. The head strips. Drill pilot holes ? joke. The head strips. Low torque setting ? - joke. The head strips. I tried to use four and had to give up as they all stripped. I couldn't even reverse them out because of guess what. They are going back to Screwfix.

Rated 1 out of 5 by from Weak screw heads Bought these to use during assembly of a deck. Where I tried to use them to temporarily hold timber in place before final fixing, they went in really well, but were extremely difficult to remove once in. 50% of the heads could not take the load and broke. Basically cheap rubbish.

Suitability for high tannin wood species?

Hi, I need screws which are suitable for larch decking. They must allow the wood to move and be resistant to the tannin. Are these suitable? What grade stainless steel are they?
Asked by: Anonymous
Hello Anonyous, The are Grade 304 Stainless Steel. The Spax Wirox Cylindrical Head Decking Screws Silver 4.5 X 60mm 250 Pack (8667T) may be a better suited option for use in larch decking. Thank you for using Q&A

Can these be used with drywall?

I need to fix some 62.5mm thick insulated plasterboard to battens so really need 85mm screws. Would these be ok or would they react with the gypsm plasterboard somehow?

Are these screws suitable for use with recycled plastic materials

Asked by: Coopermanbeith
Hello Coopermanbeith, These screws are designed specifically for use in timber, they would likely not be effective if used in plastic. Thank you for using Q&A. (LM).
